Description of problem:
Cannot launch kaffeine if amarok is running, or vice versa, amarok crashes if
kaffeine is already running.
It seems to be related to pulseaudio and not to the applications, that is why I
am reporting it here.

Moreover both applications also during normal startup reports:
$ kaffeine rocker.wm
11
*** PULSEAUDIO: Unable to connect: Connection refused

$ amarok http://www.play.cz/radio/beat128.ogg.m3u
Amarok: [Loader] Starting amarokapp..
Amarok: [Loader] Don't run gdb, valgrind, etc. against this binary! Use amarokapp.
QLayout "unnamed" added to QVBox "unnamed", which already has a layout
QLayout: Adding KToolBar/mainToolBar (child of QVBox/unnamed) to layout for
PlaylistWindow/PlaylistWindow
QObject::connect: Incompatible sender/receiver arguments
        StarManager::ratingsColorsChanged() -->
ContextBrowser::ratingOrScoreOrLabelsChanged(const QString&)
*** PULSEAUDIO: Unable to connect: Connection refused

But everything seems working fine.
I do not know how much it is related to the 1st problem.

How reproducible:
100% reproducible.

1.) Kaffein crash:
$ amarok http://www.play.cz/radio/beat128.ogg.m3u
(Amarok runs fine)

$ kaffeine rocker.wm
11
*** PULSEAUDIO: Unable to connect: Connection refused
kaffeine: pulsecore/mutex-posix.c:98: pa_mutex_unlock: Assertion
`pthread_mutex_unlock(&m->mutex) == 0' failed.
KCrash: Application 'kaffeine' crashing...
kaffeine: Fatal IO error: client killed
Unable to start Dr. Konqi

Kaffeine BackTrace:
This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents
creation of proper backtraces, or the stack frame was seriously corrupted in the
crash.
(no debugging symbols found)
Using host libthread_db library "/lib64/libthread_db.so.1".

2.) Amarok crash:
$ kaffeine rocker.wm &
(Kaffeine runs fine)

$ amarok http://www.play.cz/radio/beat128.ogg.m3u
Amarok: [Loader] Starting amarokapp..

Amarok BackTrace is attached:
  amarok_crash.0.log
  amarok_crash.1.log


Actual results:
Application Crash.


Expected results:
No Crash. Hopefully mixed sound from both applications.


Additional info:
I hope the problem is not dependent on rocker.wm, and any other file will do
:-). At least I tried another wmv with the same result.
